VKCM Volume Key Control Music

Tap your volume key "Down" then "Up" within 2sec, it is "Previous"
Tap your volume key "Up" then "Down" within 2sec, it is "Next"

This function is only available when you are using media player application

"VKCM" track adjustment way: even point or two "volume keys" !!!

At the same time cut the next song, your volume is less (or more) of the two-stage (wreck!)
Then this APP ass with ??? have ~

I'm not saying you can not first point about the volume keys "on" and then tap the volume keys "down", as is the two lower Ah!
and so:
Within two seconds "on" and "down" ... This is the next song
Within two seconds "down" and "up" ... This is a song on

If you insist on within two seconds "down" "down" ... or next, but the volume becomes less ~
If you insist on within two seconds "on" "on" ... or on one, but the volume becomes more ~


Not to cut the song, just to adjust the volume, then press the volume key slowly it ~


PS even point detection volume key twice, and only in listening to music, watch movies, play games and so on when, anyway, is press the volume keys to adjust "Media Volume" instead of "notification volume" when oh ~
